Since the rotating shaft is connected with the door handle, the rotating shaft can be driven to rotate by rotating the door handle. In addition, the range clamped by the two free arm ends of the torsion spring refers to the range contained by the restoring elasticity of the two free arm ends of the torsion spring.

The radial positioning can be achieved by limiting the pin to be immovable radially but movable axially in the axial groove as in the prior art, or by inserting a stem into the axial center hole of the pin to allow the pin to be immovable radially but movable axially.
The axial pin hole penetrates through the outer surface of the front end supporting part and can press the pin to prevent the pin from popping out of the axial pin hole, so that the top end part of the pin can be limited in the axial pin hole, but can also push the pin from the outer surface of the front end supporting part to move axially towards the inner end direction to be separated from the front end supporting part and the reversing sheet.

Theta can be 45 degrees, 90 degrees, 180 degrees or the like, and is set according to specific setting requirements, and a proper number of screens are configured correspondingly, for example, 2 screens, 4 screens or the like.
According to the technical scheme, the beneficial technical effects are found as follows:
(1) the reversing mechanism of the door handle not only can realize reversing positioning of the reversing piece by means of the pin, but also can radially position the upper end and the lower end of the pin by means of the front end supporting part and the rear end supporting part together, so that the pin cannot radially incline and the reversing piece cannot deviate when the door handle and the rotating shaft are rotated after reversing is finished;
(2) the reversing mechanism of the door handle is provided with the structure that the axial pin hole penetrates through the outer surface of the front end supporting part but can press the pin and prevent the pin from popping out of the axial pin hole, so that when the handle reversing work is carried out on a project site, only the pin needs to be pressed on the outer surface of the front end supporting part, and the door handle reversing mechanism is very convenient.
(3) Because the commutator segment is located in the accommodation space, the front end supporting part or the rear end supporting part can also press the commutator segment in the axial direction, so that the commutator segment is stable in reversing rotation, and axial runout or shaking of the commutator segment is reduced.
(4) The reversing mechanism of the door handle can also be in a structure that the extending feet of the reversing sheet are clamped by the two free arm ends of the torsion spring, and after the reversing sheet is unlocked by the pin, the reversing linkage between the rotating shaft and the reversing sheet can be realized by the two free arm ends of the torsion spring.
(5) The reversing mechanism of the door handle can also be used for clamping an extending foot and the gear of the reversing sheet by means of two free arm ends of the torsion spring, and after the reversing sheet is clamped by the pin, the extending foot can also be used as a positioning reference of the two free arm ends of the torsion spring and a limiting reference of the radial rotation range of the rotating shaft.
(6) In the daily use of the lockset product, the automatic reset (always in a horizontal position) of the door handle can be realized by means of the torsion spring.
The technical scheme can be that the supporting component comprises an upper cover and a base which are arranged in front and back, the front end supporting part is arranged on the upper cover, the rear end supporting part is arranged on the base, and the upper cover is connected with the base. In this way, the mounting stability of the members such as the commutator segments and the torsion springs arranged in the accommodating space between the front end support portion and the rear end support portion in the axial direction is enhanced by the connecting structure between the upper cover and the base. In addition, the upper cover, the base and the components arranged in the accommodating space can be assembled into an integrated module with an independent structural relationship, so that modular production of door handle products is facilitated, and production efficiency is improved.
The door handle reversing mechanism is also provided with a lock panel, and the following technical scheme can be further adopted between the base and the lock panel:
the first optional technical scheme is that the lock further comprises a lock panel, and the base and the lock panel are integrally formed. This simplifies the construction and assembly of the lock.
The second optional technical scheme is that the lock further comprises a lock panel, the base and the lock panel are arranged separately, the base is detachably connected to the inner side of the lock panel through screws, and a panel hole corresponding to the rotating shaft is formed in the lock panel. In this way, the lock panel and the base may be made of different materials, for example, the base may be made of a metal material to provide a relatively stable positioning of the rotating shaft, and the lock panel may be made of a non-metal material such as plastic or resin for cost saving. In addition, the lock panel can also be rich in different colors and textures by adopting a surface treatment process different from that of the base. The split structure between the base and the lock panel enables the arrangement of the base and the lock panel on structure and appearance to be more flexible and diversified.
In order to enrich the appearance of the lockset, the lock further comprises a lock panel and a decorative cover, wherein the decorative cover is positioned outside the lock panel and detachably connected on the lock panel, the lock panel and the decorative cover are respectively provided with a through hole corresponding to the rotating shaft, and the through hole on the lock panel and the through hole on the decorative cover are positioned on the same axis. The decorative cover and the lock panel are of a split structure, so that the decorative cover can be configured with different colors and materials from the lock panel, and the appearance of the lock can be enriched.
In order to make the torsional spring can have relatively stable axial positioning in the axis of rotation, further technical scheme can be, the axis of rotation includes the main shaft body, on the main shaft body along radial convex protruding limit, keep off the position along the axial setting and connect in on the protruding limit, keep off position and protruding limit and be located between the preceding axle head and the back axle head of axis of rotation, keep off the position with radially dodge the space between the main shaft body, the circle spring main part of torsional spring arranges in radially dodging in the space.
The protruding edge may be a structure integrally formed with the spindle body or an independent member that is independent from the spindle body and is inserted into the spindle body. In addition, the convex edge protrudes in the radial direction, and the above feature defines the structural feature of the convex edge, the convex edge is a solid extending in the direction perpendicular to the axis of the spindle body, and the convex edge not only has the axial thickness, but also has the radial width.
The gear and the protruding edge are located between the front shaft end and the rear shaft end of the rotating shaft. The above feature defines the arrangement positions of the shift and the protruding edge, and the shift and the protruding edge may be located at any position between the front shaft end and the rear shaft end of the rotating shaft, but may not be located on the front shaft end and the rear shaft end of the rotating shaft, so as to make room for the fitting of the front support portion and the rear support portion with the main shaft body, respectively.
Wherein a coil spring main body of the torsion spring is arranged into the radial escape space. Thus, the radial avoiding space becomes an arrangement space of the coil spring main body of the torsion spring, and the torsion spring can be axially positioned. The torsional spring is stably positioned on the rotating shaft and assembled together with the rotating shaft into an independent module, so that the lockset is convenient to assemble.
Further technical scheme can also be, keep off the position and keep off the position including the first fender position and the second of branch putting, extend the foot and extend the foot including the first extension foot and the second of branch putting, first extension foot is located the side of first fender position, the second extends the foot and is located the side of second fender position, for the center of rotation of axis of rotation the centre of rotation angle of the centre gripping centre of a circle angle of two free arm ends of torsional spring is greater than 90.
In order to limit the rotation stroke of the rotating shaft, a further technical scheme may be that the rotating shaft further includes a radially protruding limiting protrusion, and when the rotating shaft rotates relative to the commutator segment, the limiting protrusion can abut against the extending leg provided on the commutator segment to limit the rotation stroke of the rotating shaft. The limiting bulge is a solid extending along the direction vertical to the axis of the spindle body, and has axial thickness and radial width. Thus, when the commutator segments are fixed and can not rotate, the extending feet on the commutator segments limit the rotation stroke of the rotating shaft, and the rotating shaft can only rotate freely in a specific rotation stroke and can not rotate for commutation.
In order to enable the rotating shaft to rotate more stably and smoothly, a further technical scheme can be that bearings are respectively arranged between the front shaft end of the rotating shaft and the front end supporting part of the supporting component and between the rear shaft end of the rotating shaft and the rear end supporting part of the supporting component and are connected through the bearings. In this way, the bearings arranged in the front-rear direction can provide a front supporting point and a rear supporting point for the rotating shaft, thereby reducing or avoiding the occurrence of significant shaking (virtual position) when the door handle swings in the front-rear direction with the rotating shaft as a fulcrum. In addition, the arrangement of the bearing can reduce the sliding friction force between the rotating shaft and the front end supporting part and between the rotating shaft and the rear end supporting part, so that the rotating shaft is smoother when rotating.
In order to enable the pin to elastically move in the axial direction, a further technical scheme may be that an axial spring hole arranged along the axial direction is further provided at an eccentric position on the rear end support portion, a pin return spring is accommodated in the axial spring hole, and the pin can be pressed into the axial spring hole and pressed against the pin return spring. Therefore, the pin can axially and elastically move under the action of the pin return spring, and the pin can extend into the clamping position to clamp the commutator segment by means of the pin return spring. In addition, the axial spring hole not only can radially position the pin, but also can provide a retreating space for the pin to retreat and separate from the clamping position of the commutator segment.
In order to simplify the installation operation of the door handle and ensure the installation stability of the door handle, a further technical proposal is that the door handle is arranged separately from the rotating shaft, a threaded hole is arranged on the door handle, an axial through hole is arranged at the axial center of the rotating shaft, and a bolt passes through the axial through hole of the rotating shaft and is connected to the threaded hole of the door handle so as to detachably connect the door handle and the rotating shaft. In this way, the door handle and the rotating shaft adopt a detachable connecting structure, so that the installation between the rotating shaft and the supporting component, the commutator segment and other members is greatly simplified, and the axial virtual position between the rotating shaft and the door handle can be eliminated through the fastening and connecting action of the bolt, so that the door handle and the rotating shaft are stably connected, and the use safety of a user is improved.
The technical scheme can also be that a spline type matching structure is arranged at the connecting part between the door handle and the rotating shaft. Therefore, the spline type matching structure can reduce or avoid radial slipping between the door handle and the rotating shaft, and can also reduce the virtual positions of the door handle and the rotating shaft in the radial direction, so that the door handle and the rotating shaft are connected more stably, and the use safety of a user is further improved.

In this way, the radial clearance space 24 serves as a space for disposing the coil spring main body 71 of the torsion spring 7, and the torsion spring 7 can be positioned in the axial direction. The torsion spring 7 is stably positioned on the rotating shaft 2 and assembled with the rotating shaft 2 into an independent module, so that the lockset is convenient to assemble. Two free arm ends (72, 73) of the torsion spring 7 extend out of the escape space 24 and are clamped by elastic force at positions on both sides of the gear 22.
As shown in fig. 6, 7 and 8, the segment 5 includes a segment main body 50, a segment through hole 53 that is provided in a central region of the segment main body 50 and is free from the spindle body 20, and a pair of axially extending legs (52, 52 a) and two locking portions (51, 51 a) that are adapted to the pin 6 and through which the pin 6 can pass are provided on the segment main body 50. The screens (51, 51 a) are groove-shaped positioning grooves arranged on the periphery of the segment main body 50 of the commutator segment 5. In other embodiments, the detent may be a hole-shaped positioning hole disposed at a side edge of the segment 5. Wherein the extending feet (52, 52 a) and the blocking positions (51, 51 a) are respectively arranged at the left side and the right side of the sheet through hole 53. The commutator segment 5 is sleeved on the front shaft end 20a of the main shaft body 20 through a segment through hole 53 and leans against the convex edge 21. The extending feet (52, 52 a) are positioned outside the radial avoiding space 24 and on the side of the gear 22, and the gear 22 and the extending feet (52, 52 a) are simultaneously positioned in a range clamped by two free arm ends (72, 73) of the torsion spring 7. The clamping central angle Q of the two free arm ends (72, 73) of the torsion spring 7 is greater than 90 DEG with respect to the rotation center of the rotation shaft 2. In other embodiments, for example, when the clamping gap between the two free arm ends (72, 73) of the torsion spring 7 is relatively small, for example less than 45 °, the gear 22 and the extension foot can each be a projecting component. If the clamping range between the two free arm ends (72, 73) of the torsion spring 7 is relatively large, for example greater than 90 °, the gear 22 and the extension leg may each be a protruding member, or may each be two protruding members disposed on the left and right. For example, the gear 22 includes a first gear and a second gear (not shown), and the extension legs include a first extension leg 52 and a second extension leg 52a, which are separately arranged, the first extension leg 52 is located on the side of the first gear 22, and the second extension leg 52a is located on the side of the second gear.
As shown in fig. 3 and 4, the support assembly includes an upper cover 3 and a base 4 arranged in a front-back manner, the front end support 30 is disposed on the upper cover 3, the rear end support 40 is disposed on the base 4, and the upper cover 3 and the base 4 are connected by a screw 6. A receiving space a is formed between the upper cover 3 and the base 4, the rotating shaft 2 is rotatably arranged on the upper cover 3 and the base 4 through a front shaft end 20a and a rear shaft end 20b, and the rear shaft end 20b of the rotating shaft 2 is connected with the door handle 1; the reversing sheet 5 and the torsion spring 7 are arranged in the accommodating space a and are sequentially sleeved on the rotating shaft 2. In this way, the installation stability of the commutator segment 5 and the torsion spring 7 in the axial direction is enhanced by the connecting structure between the upper cover 3 and the base 4. In addition, the upper cover 3, the base 4 and the components arranged in the accommodating space a can be assembled into an integrated module with independent structural relationship, so that the modular production of door handle products is facilitated, and the production efficiency is improved. The front end support portion 30 is provided with an axial pin hole 31 corresponding to the pin 6, the tip end portion of the pin 6 can be inserted into the axial pin hole 31, and the axial pin hole 31 penetrates the outer surface of the front end support portion 30 but can press the pin 6 so as not to be ejected from the axial pin hole 31. An axially arranged axial spring hole 41 is also provided at an eccentric position on the rear-end support 40, a pin return spring 60 being accommodated in the axial spring hole 41, the pin 6 being able to be pressed into the axial spring hole 41 and against the pin return spring 60. Thus, the pin 6 can axially and elastically move under the action of the pin return spring 60, and is reset by the pin return spring 60 to extend into the detent (51 or 51 a) to block the commutator segment 5. In addition, the axial spring hole 41 not only can radially position the pin 6, but also can provide a retreating space for the pin 6 to retreat and disengage from the detent (51 or 51 a) of the segment 5. According to the above technical solution, it can be found that the upper and lower ends of the pin 6 are radially positioned by the front end support 30 and the rear end support 40 together, so that when the door handle 1 and the rotating shaft 2 are rotated after reversing is completed, the pin 6 does not incline radially, and the reversing piece 5 does not shift. In addition, because the commutator segment 5 is located in the accommodating space a, the front end supporting part 30 can press the commutator segment 5 in the axial direction, so that the commutator segment 5 is stable in reversing rotation, and axial runout or shaking of the commutator segment 5 is reduced.
According to the technical scheme, the reversing mechanism of the door handle works as follows:
when the pin 6 is in the free state, the pin 6 extends into one of the detents, for example detent 51, and the tip end of the pin 6 extends into the axial pin hole 31, and the tail end of the pin 6 is pressed into the axial spring hole 41 and against the pin return spring 60. At this time, the commutator segment 5 is clamped and can not rotate, when the rotating shaft 2 is rotated clockwise to drive the torsion spring 7 to rotate, the rotating shaft 2 can rotate relative to the commutator segment 5, the left free end 72 of the torsion spring 7 abuts against the left extending foot 52a and can not move, and the free end 73 of the right end of the torsion spring 7 is driven by the gear 22 to rotate along with the rotating shaft 2 and leave the right extending foot 52, or vice versa. The extension legs (52, 52 a) can serve as a positioning reference for the two free arm ends (72, 73) of the torsion spring 7 and a limit reference for the radial rotation range of the rotating shaft 2. When the rotating shaft 2 stops rotating, the torsion spring 7 allows the rotating shaft 2 to reset, and meanwhile, the door handle is automatically reset (always in a horizontal position).
When the handle reversing work is implemented on an engineering site, only the outer surface of the front end supporting part 30 needs to press the pin 6, the pin 6 retreats in the axial spring hole 41 and enables the top end part of the pin to be separated from the clamping position 51 of the commutator segment 5, the pin 6 is clamped by the two free arm ends (72 and 73) of the torsion spring 7 to extend the pins (52 and 52 a) so that the rotating shaft 2 can drive the torsion spring 7 and the commutator segment 5 to rotate together, when the rotating shaft 2 and the commutator segment 5 rotate for 180 degrees, the pin 6 pops out for resetting, and the reset pin 6 stretches into the other clamping position 51a to clamp the commutator segment 5. The reversing operation of the door handle 1 is completed, which is very simple.
In order to limit the rotation stroke of the rotating shaft 2, as shown in fig. 5, 7 and 8, the rotating shaft 2 further includes a radially protruding limit protrusion 23, and the limit protrusion 23 is disposed on the shift position 22. Thus, when the segments 5 are locked by the pins 6 and cannot rotate, and the rotating shaft 2 rotates relative to the segments 5, the limit protrusions 23 can abut against the extension legs (52, 52 a) provided on the segments 5, and can limit the rotating stroke of the rotating shaft 2. The rotary shaft 2 can only rotate freely in a specific rotary stroke, and cannot rotate 180 degrees for reversing.
As shown in fig. 3, bearings (8, 8 a) are respectively disposed between the front shaft end 20a of the rotating shaft 2 and the upper cover 3, and between the rear shaft end 20b of the rotating shaft 2 and the base 4, and are connected by the bearings (8, 8 a). The bearings (8, 8 a) are ball bearings or slide bearings. In this way, the bearings (8, 8 a) arranged in a front-rear direction can provide a front supporting point and a rear supporting point for the rotating shaft 2, thereby reducing or avoiding the occurrence of significant shaking (virtual position) when the door handle 1 swings in the front-rear direction about the rotating shaft 2 as a fulcrum. In addition, the arrangement of the bearings (8 and 8 a) can reduce the sliding friction force between the rotating shaft 2 and the upper cover 3 and the base 4, so that the rotating shaft 2 rotates more smoothly.
As for the connecting structure between the rear shaft end 20b of the rotating shaft 2 and the door handle 1, a structure in which the rotating shaft 2 and the door handle 1 are integrated with each other may be employed. Alternatively, as shown in fig. 3 and 4, the door handle 1 is disposed separately from the rotating shaft 2, a threaded hole 100 is provided at the shaft end 10 of the door handle 1, an axial through hole 25 is provided at the axial center of the rotating shaft 2, and a bolt 102 is inserted through the axial through hole 25 of the rotating shaft 2 and connected to the threaded hole 100 of the door handle 1 to detachably connect the door handle 1 and the rotating shaft 2. Therefore, during installation, the rotating shaft 2, the commutator segments 5 and the torsion spring 7 are assembled firstly and then installed between the upper cover 3 and the base 4, and the rear shaft end 20b of the rotating shaft 2 extends out of the base 4 to be connected with the door handle 1. Of course, in other embodiments, it is also possible to connect the rear axle end 20b of the rotary axle 2 after the axle end 100 provided on the door handle 1 has been inserted into the base 4. The split structure greatly simplifies the installation between the rotating shaft 2 and the supporting component, the commutator bar 5 and other components, and can eliminate the axial virtual position between the rotating shaft 2 and the door handle 1 through the fastening connection action of the bolt 102, so that the door handle 1 and the rotating shaft 2 are firmly connected, and the use safety of a user is improved. In addition, a spline-type fitting structure is provided at a connection portion between the shaft end 10 of the door handle 1 and the rotating shaft 2. Therefore, the spline type matching structure can reduce or avoid radial slipping between the door handle 1 and the rotating shaft 2, and can also reduce the virtual positions of the door handle 1 and the rotating shaft 2 in the radial direction, so that the door handle 1 and the rotating shaft 2 are connected more stably, and the use safety of a user is further improved. Since the rotating shaft 2 is connected to the door handle 1, rotating the door handle 1 can rotate the rotating shaft 2.
The door handle reversing mechanism is also provided with a lock panel 9, and the following technical scheme can be further adopted between the base 4 and the lock panel 9:
a first alternative solution is that the base 4 and the lock panel 9 are integrally formed. This simplifies the construction and assembly of the lock.
A second alternative solution is that, as shown in fig. 3 and 4, the base 4 is disposed separately from the lock panel 9, the base 4 is detachably connected to the inner side of the lock panel 9 by a screw 6, and the lock panel 9 is provided with a panel hole 90 corresponding to the rotation shaft 2. Thus, the lock panel 9 and the base 4 may be made of different materials, for example, the base 4 may be made of a metal material to provide a relatively stable positioning of the rotating shaft 2, and the lock panel 9 may be made of a non-metal material such as plastic or resin for cost saving. In addition, the lock panel 9 may have different colors and textures by using a surface treatment process different from that of the base 4. The split structure between the base 4 and the lock panel 9 makes the arrangement of the base and the lock panel more flexible and diversified in structure and appearance.
A decoration cover 91 is further provided on the outer side of the lock panel 9, the decoration cover 91 is detachably connected to the lock panel 9, through holes 910 corresponding to the rotating shafts 2 are provided in the decoration covers 91, and the panel hole 90 in the lock panel 9 and the through hole 910 in the decoration cover 91 are located on the same axis. A spigot positioning structure is arranged between the decorative cover 91 and the lock panel 9, the spigot positioning structure comprises a recess 911 arranged on the decorative cover 91 and an annular protrusion 901 arranged on the lock panel 9, and when the spigot positioning structure is positioned, the annular protrusion 901 is inserted into the recess 911 to realize radial positioning between the two components. Of course, in other embodiments, the recess 911 and the annular protrusion 901 may be interchanged, that is, the recess 911 is disposed on the lock panel 9, and the annular protrusion 901 is disposed on the decorative cover 91. Thus, the decorative cover 91 can be provided with a different color and material from those of the lock panel 9, thereby making it possible to enrich the appearance of the lock.
